I helped Mike with a couple of transmitter problems:

1.  TX6, one of the Thompson 250kw transmitters, had a  trip off last night due to low water flow.   The limit switch seemed to be set a little too sensitive and was readjusted.

2. TX5, the HC100 100kw transmitter, had a bad module.  The transmitter can operate normally with up to four faulty modules, but it is good to repair them when there is a break in transmissions.  The main switching IGBT (transistor) was shorted, so I replaced the IGBT and installed the module back into the HC100.

The HC100 module has been repaired and will be tested on the module tester before returning it to service.

There is quite a bit of technial information on my computer that might be valuable for TWR Guam to have.  Since the time of our departure is only a few days away, I spent a few hours sorting through that information and transferring the most helpful information to TWR Guam transmitter site’s technical files.

The trucking company called to inform us that the containers would not be picked up today, because there had been too much rain.  They thought the risk of getting stuck on the dirt roads at the site.  They were basing their assessment on the rain they were seeing on the north end of Guam.  Mike informed them that there was no rain on the south end of the island.  Unfortunately, it was too late for them to change their plans for the day.  We wonder what Monday will be like after an anticipated rainy weekend?

If the trucking company waits much longer, they might not be able to find this trailer that they parked at the transmitter site.
